Description

Expanded mobile power unit

The invention relates to an extended mobile power source, which is a portable carrying and charging and discharging device, which can increase or decrease the total battery capacity according to the use requirement, and then charge or power the mobile digital device through the transmission port.

Currently, mobile digital devices, such as mobile phones, notebook computers, digital cameras, audio players, and the like, use a charge and discharge battery as a source of power when used.

Generally, when charging a battery used in an action digital device, it is necessary to charge the battery through the equipped charger and use the local AC power to convert to a certain voltage level; in an environment where the city AC power cannot be obtained, It will cause difficulty in charging or cause the mobile device to be interrupted.

Therefore, there is a charging device that can be carried around, commonly known as "mobile power", which allows the user to charge or power the mobile digital device in an environment where no AC power is available in the city.

The current mobile power supply is composed of a rechargeable battery and a control circuit, and is packaged together in a casing, and then divided according to the total battery capacity. The small-capacity mobile power products are light and thin. The advantage, but there are shortcomings of short use time; large-capacity mobile power products are bulky and cumbersome, causing inconvenience in carrying, and because the rechargeable battery has a limitation on the age and number of times, when the mobile power efficiency is not When it is good or damaged, it can only be discarded in the whole group.

In view of the above-mentioned shortcomings of the conventional similar device, the present invention is designed to provide a user's battery capacity requirement, and the user can flexibly increase or decrease the total battery capacity by means of a combination of battery packs, and can further manage The volume and weight when carrying, if necessary, only through the update of the battery pack, can improve the performance of the mobile power supply, thereby reducing the waste of resources.
